Note 4. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD.
Note 5. When IPGA Gain is changed, this typical value changes between 8kΩ and 11kΩ.
Note 6. Input voltage is proportional to AVDD voltage. Vin = 0.06 x AVDD.
Note 7. Output voltage is proportional to AVDD voltage. Vout = 1.2 x AVDD at Full-differential output.
Vout = 0.6 x AVDD at Single-end Output
Note 8. Output voltage is proportional to AVDD voltage. Vout = 0.582 x AVDD.
Note 9. Output voltage is proportional to AVDD voltage. Vout = 0.897 x AVDD at Full-differential output.
Note 10. BEEP-AMP can’t output more than this maximum voltage.
Note 11. Maximum Input Voltage is proportional to AVDD voltage. Vin = 0.6 x AVDD.
Note 12. When ALC2 Gain is changed, this typical value changes between 22kΩ and 26kΩ.
Note 13. Output Voltage is proportional to AVDD voltage. Vout = 0.588 x AVDD.
Note 14. When the output pin drives a capacitive load, a resistor should be added in series between the output pin and
capacitive load.
